350 TPI, nitrous, heads, cam, D-1SC procharger, 3.73 gears...to name the bigger upgrades to my motor

This is all about to go on my TPI and I'm going to need a tune. What do I do? Ive been reading and looking at sites but I'm a little confused. I've read some where here about the timing having to be severely adjusted due to the procharger?

Someone lead me in the right direction.

 

First let me start by saying if your going to be using forced induction those 24lbs injector are way to small.
Yes you will need a tune. Are you planning on doing the tune your self?
Your timing and fuel will need to be adjusted,

 

The injectors will be upgraded. Already on the list

Im having the shop thats doing my work, also dyno and tune it. So no, I wont be doing the tune
